Custom Texture Shader in Three.js

You are still using the old syntax for uniforms

var uniforms = {
    texture1: {
        type: "t",
        value: 0,
        texture: THREE.ImageUtils.loadTexture("texture.jpg")
    }
};

This is the new syntax

var uniforms = {
    texture1: { type: "t", value: THREE.ImageUtils.loadTexture( "texture.jpg" ) }
};
